Habitat/ Lifestyle

free living; bottom dwellers. scavengers in rivers, lakes, streams; some parasitic

free-living; marine or fresh water

some parasitic; free-living in lakes and ponds

all parasitic; live in body fluids of host

Structure

jelly-like; changes shape

covered by hard pellicle (shell)

whip-like tail called flagella

all parasitic; live in body fluids of host

Nutrition

decaying organic matter; phagocytosis, absorption

takes in food through oral groove and mouth pore

whip-like tail called flagella

conical top

Reproduction

binary fission; can form cysts under adverse conditions

binary fission; conjugation

binary fission

complex life cycle involves many hosts, sexual and asexual phases

Significance

causes amoebic dysentery

 

Trypanosoma lives in blood of host; causes African sleeping sickness; transmitted by tsetse fly. Trichonympha lives in the gut of termites with bacteria to convert cellulose to soluble fiber

Plasmodium causes malaria. symptoms include fever, anemia, destruction of RBCs

starch

starch

Significance

food producer; plankton; important part of food chain

used in ice cream, sherbet, cream cheese to give a smooth, stable consistency

carageenan used in cosmetics, gelatin capsules, cheeses; some produce calcium carbonate for coral reefs

silica in shells used in abrasives, detergents, paint removers, fertilizers (diatomaceous earth); responsible for bulk of world’s photosynthesis

red tides (population explosion), produce toxins that cause respiratory problems in humans if ingested (usually by eating shellfish)

both plant and animal like characteristics

Fungi

 

Zygomycota
Ascomycota
Basidiomycota
Deuteromycota
Lichen

Common Name

terrestrial molds

sac fungi (largest group)

club fungi

imperfect fungi

 

Examples

black bread molds (Rhizopus)

truffles, morels, yeast, penicillium; powdery mildews

mushrooms, puffballs, shelf fungi, rusts, smuts

ringworm, athlete’s foot, yeast

reindeer moss

Structure

rhizoids: hyphae used for anchorage and absorption of nutrients

spores formed in sac (ascus)

visible portion: fruiting body composed of stalk, cap, and gills

 

crustose lichen (bare rock); foliose lichen (leaflike); fruticose (shrubby). mutualistic relationship between algae and sac fungus

Significance

found on fruit, bread. whitish or grayish in appearance

yeast cause bread to rise; blue green molds used in cheeses, produce antibiotics; responsible for chestnut tree blight; Dutch elm disease

mushrooms collected as food; rusts and smuts are parasitic fungi that attack grains

Candidia albicans responsible for thrush, moniliasis

pioneer species: can survive harsh environmental conditions. indicator species: extremely sensitive to air pollution
